HORSESHOE ATTACHMENT.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed February 5, 1907. Serial No. 355.934.

One of the objects of the invention is to provide a simple and cheap attachment, which can be readily fitted to any'sized shoe and readily clamped thereto.

Another object of my invention is to provide the clamping or fastening mechanism of such a character that no cross strains are transmitted to the shoe. In devices of this character heretofore used, in which a spreading wedge is employed, the two limbs of the shoe are either pried apart or drawn together, and as the shoe is of malleable iron it gradually yields to the strain so that it not only pulls the shoe out of its original shape, but it injures the hoof of the animal.

The various features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which:-

Figure 1 is a bottom plan view of the shoe, showing my attachment. Fig. 2 is a top plan view. Fig. 3 is a section on line x,-a3, Fig. 1. Fig. 4 is a section on line w,w, Fig. 2. Fig. 5 is a section on line v,o, Fig. 2.

1 represents the shoe.

2, 3, represent the right and left hand pieces constituting the attachment which are counter parts of one another in construction, and which are clamped to the shoe by means of the bolt 4. The pieces 2, 3, are straight bars, having at their inner ends the opposing sleeves 5, 6, into one of which the bolt 4 is screw threaded. Bolt 4 is provided with a socket or shoulder section 7. The outer ends of the pieces 2, 3, are provided with the flanges 8, 9.

It will-be understood that the attachment lies on the under side of the shoe and that the flanges 8, 9, extend upward on the outside of the shoe and overlap slightly the top surface of the shoe at the heels, shown in Fig. 2, but do not contact with the hoof of the animal. The calks or pins 10 are preferably provided at the opposite ends of the members 2, 3.

The intermediate portions of the pieces 2,,3, have formed thereon the opposing screw threaded lugs 11, 12, which lie on the inside of the shoe about mid-way between the heels and the toe of the shoe. Into these screw threaded lugs 11, 12, are screwed the bolts 13, 14,

the heads 15, 16, of which are formed with socket faces engaging the opposite inner edges of the limbs of the shoe, see Fig. 4.

In applying the attachment, 2, 3, represent the clamping members or bars extending substantially from the toe to the heel of each limb and suitably attached thereto. One of the pieces, say 2, is fitted to one limb of the shoe, as follows, the flange 9 is brought into engagement with the outer edge of the heel of the shoe and the bolt 13 is adjusted until its socket head 15 comes to a bearing against the inner edge of the shoe about mid-way from the heel to the toe. The other piece 3 is likewise independently fitted to the other limb of the shoe. ed sleeves 5, G, is then tightened so as to spread the ..pieces 2, 3, at the toe of the shoe. The inner end of the piece 2 is forced outward, and the bolt head 15 forming a sort of a fulcrum bearing against the intermediate portion of that limb of the shoe, it follows that the flange on the outer end of the piece 2 is forced inward against the outer edge of the heel of the shoe. The action of tightening up the bolt 4 has a like effect upon the opposite piece 3. But it will be observed that the members 2, 3, are each independently clamped upon the opposite limbs of the shoe, that is, the outer end of each limb of the shoe is forced inward, the resistance to the clamping action being on the inner portion of the intermediate part of the same limb. In order to prevent the bolt 4 from loosening, 1 provide one of the screw threaded flanges, say 5, with a slot 17 giving access to one end of the bolt 4, preferably the non-screw threaded end. This non-threaded end is provided with one or more diametrical pin holes. The bolt 4 is turned up until the attachment is satisfactorily secure, and enough to present one of the diametrical holes 18 to the slot 17 Whenapin 19 is inserted into the hole, the bolt 4 is then unscrewed a very slight turn, which brings the upper end of the pin 19 against the shoulder 20 formed on the innerwall of the slot 17, thus constituting a nut lock which effectually prevents the bolt 4 from becoming unscrewed, and it also forms The bolt 4 in the screw threadi an interlock between the two bars 2, 3, which holds the bars in fixed relative position.

Having described my invention, I claim:

1. A calk attachment for horseshoes, consisting of a clamping member for each limb secured to the heel and toe thereof, and having a fulcrum engaging an intermediate part of the limb, and means for forcing the ends of said members in opposite directions,substantially as described.

2. A calk attachment for horseshoes, consisting of a clamping member for each limb, the opposite ends of which engage the opposite edges thereof, said member having a fulcrum engaging an intermediate part of said limb, and means engaging the ends of said members on one side of the fulcrum to clamp the parts together, substantially as described.

3. A call: attachment for horseshoes, consisting of a clamping member for each shoe limb, said member extending substantially from toe to heel, and having its opposite ends provided with bearings one of which engages upon one edge and the other bearing upon the opposite edge of said limbs, said member having a fulcrum engaging an intermediate part of said limb, and means for forcing the ends of said member in opposite directions, substantially as described.

4. A ealk attachment for horseshoes, consisting of a clamping member for each shoe limb, said member extending substantially from toe to heel, the opposite ends of said member being provided with bearings one of which engages upon one edge and the other bearing upon the opposite edge of said limb, said member havinga fulcrum bearing against one edge of an intermediate part of said limb, and a clamping bolt engaging the ends of said members on one side of the fulcrums, substantially as described.

'5. A calk attachment for horseshoes, consisting of a clamping member for each shoe limb, extending substantially from toe to heel and lying under the limb, the opposite ends of said member being provided with upwardly extended flanges adapted to form bearings against the edges of said limb at the toe and heel, said limb having a fulcrum bearing against the edge of an intermediate part of said limb, and clamping means, substantially as described.

6. A calk attachment for horseshoes, consisting of a clamping member for each limb, having its opposite ends one end engaging upon one edge and the other bearing upon the opposite edge of the heel and toe parts of the limb, and an adjustable fulcrum bearing against the edge portion of an intermediate part of said limb, and means for clamping said limbs on their fulcrums, substantially as described.

A calk attachment for horseshoes, consisting of a clamping member for each limb, extending substantially from toe to heel on the under side of the 51106,. the opposite ends of said member being provided with upwardly ex tended flanges, adapted to form bearings respectively against the opposite edges of said limbs at toe and heel, said limb having a fulcrum bearing adjustable to and from the edge of the limb intermediate the toe and heel, and means for clamping the said limbs on their fulcrums, substantially as described.

8.
